"I’m so glad I called HD mechanical to have my thermostat fixed. We set a time to meet up and he was there on time and very professional. He was very thorough with his work and explained to me all the work he performed. He even checked and serviced my unit, showing me that my filter needed to be changed. Would definitely recommend to anyone who needs and service/repairs done."

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

"They were AWESOME. Same day service and quickly diagnosed the issue (blown transformer, since my furnace does not have a fuse). The guys were professional, courteous, explained what they were doing and why, and couldn't have been nicer. They finished the job quickly, and even installed the NEST which I had done wrong the first time, hence the need to call them. :-P"

"West Tech Mechanical Services (Joe Gonsalez) did an excellent job. This is the best investment that I have ever made for our quality of life in our home. Joe's attention to detail is evident in the care and consideration that he put into the duct work in the installation process. He thoroughly explained to me the importance of the duct work: location and size of the ducts to maximize the efficiency of the system that he was installing. Our home is an old home, and I really appreciate the care that he took in the installation process. I obtained 3 quotes for this job and West Tech Mechanical was in the middle. All the persons that came to our house were nice people. However, Joe's obvious attention to detail and how he explained the job is what convinced me that he and his company were the right people for the job. For a home owner that is considering the installation of a central air and heat system in their home or, any work for that matter on an existing heat and air system, I highly recommend this company as one that should be considered."

"This company was the second i had out to look at repairing our tankless hot water heater. For over a week the hot water would turn off randomly.  Baltica was my second opinion  for the repairs and i felt really lucky to have found them on Angie's list. The first company told me i needed to replace the entire 5 year old unit for $2200.00. Baltica answered all my questions before coming out,  Marius assessed the condition once  he came out,  the unit was flushed and clean out valves were installed he was very professional.  How nice to work with a company that stands behind their service.

"That worked out very well. He did very well. They've been working fine ever since. It's been about 6 months now. It all worked very well. I gave him the go ahead on September 19th. On the 26th, I received a courtesy followup from him, after it had been done. I had about 6 different contenders bid. Some of them were more than he was. One of them actually had a 10 year warranty on parts and labor. Southland was less in terms of the warranty. Their price was generally lower. I have subsequently seen offers for much less on Angie's List. I guess it was just the timing. So far everything has been great. No problems. They showed up right when they said they would. I'm planning to use them in the future. It turns out that the units they installed would soon be upgraded so they can respond to Amazon's voice controlled robot (Alexa). He said that these components will have Alexa capability in February. As soon as they are available, I will be contacting Southland again to come out and upgrade the air conditioning, so I can say to Alexa to turn the heat up or down and do it all by voice control. I have smart devices all throughout the house.

Install Boiler questions, answered by experts

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.
